High as a 24-story building
If you stood at the base of Alder Dam, it would tower 285 feet above you and extend 45 feet below you. It was one of the tallest dams in the United States when Tacoma Power finished it in 1945. It’s four and a half football fields long.

Water’s power
Water from Alder Lake plunges down large pipes, called penstocks, and spins two turbine generators inside the powerhouse. The resulting electricity travels along a 25 mile-long transmission line to Tacoma.

Once upon a glacier
Five glaciers on Mount Rainier feed the Nisqually River, which flows 27 miles before reaching Alder Lake. Melting glacial ice gives the river and lake a unique color.

Dam strong
The dam was constructed with enough concrete to fill 42,000 dump trucks. Alder Dam is 15 feet thick at the top and 120 feet thick at the base.
